संपत्ति वर्ग

Question

के लिए सेटर नहीं मिला है, अब मैं जेएसएफ, वसंत और ibatis के साथ नमूना आवेदन लिखता हूं। मैं फेसलेट का उपयोग करता हूं और template.xhtml, header.xhtml, menu.xml, login.xhtml और होम पेज लिखता हूं। लॉगिन के बाद, मुझे यह त्रुटि मिली।

ब्राउज़र में,

Setter not found for property class 
    + Stack Trace 
    + Component Tree 
    + Scoped Variables 

कंसोल में,

मेरे template.xml,

<div class="head">  
    <ui:include src="header.xhtml"></ui:include> 
    <div> 
    <table border="0" class="normal" height="500px" align="center" bgcolor="#F4FFE4"> 
     <tr> 
     <td width="13%"> 
      <ui:include src="menu.xhtml" /> 
     </td> 
     <td width="87"> 
      <ui:insert name="body" /> 
     </td> 
     </tr> 
     </table> 
    </div> 
    <ui:include src="footer.xhtml"></ui:include> 

मेरे मुख पृष्ठ (SPAR02.xhtml),

<ui:define name="head"> 
    <title>Top Menu</title> 
    </ui:define> 
    <ui:define name="body"> 
    <font size="5">Welcome</font> 
     You can search user informations, update or delete them and can add new user. 
    </ui:define> 

मुझे कोई गलती नहीं मिल रही है, कोई मेरी मदद करता है।

Answer 1

फेसलेट्स संपत्ति को class पर सेट करने का प्रयास कर रहा है जो इस संपत्ति को स्वीकार नहीं करता है। अधिकांश समय, एचटीएमएल class विशेषता के लिए संपत्ति styleClass है।

मुझे आपके द्वारा दिए गए कोड में समस्या नहीं दिखाई देती है। समस्याएं चेहरे के पृष्ठ में कहीं भी हो सकती हैं।

Answer 2

मैं वसंत में एक ही त्रुटि,

public static void setFileName(String fileName) { 
    LogFile.fileName = fileName; 
} 

था

<bean id ="logfile" class = "A.B.C.LogFile" > 
    <property name ="fileName" value ="${fileName}" /> 
</bean> 

समाधान सिर्फ विधि से स्थिर दूर करने के लिए है:

// without static 
public void setFileName(String fileName) { 
    LogFile.fileName = fileName; 
} 

कि वह इसे सेट कर सकते हैं के बाद :)
